Description

Technical Field

[0001] This invention relates to the field of nut cutting equipment technology, and in particular to a highly compatible nut double-sided continuous cutting machine. Background Technology

[0002] Nuts have hard shells and contain edible kernels. Examples include walnuts, pecans, and macadamia nuts. Nuts are the essence of plants, generally rich in nutrients, containing high levels of protein, oils, minerals, and vitamins, and have excellent effects on human growth and development, strengthening the body, and preventing diseases.

[0003] Before roasting, nuts need to be slit in their hard shells to allow for better flavor absorption and easier opening later. Current techniques involve slits made manually or mechanically. However, because nuts are round, different sizes and types of nuts often have different shapes and dimensions, making it difficult to fix and cut them properly.

[0004] Defects and shortcomings of existing technology:

[0005] 1. Nuts need to be cracked before processing. The existing production methods mostly involve cracking the shells, which easily leads to broken kernels and makes it difficult to ensure a neat and beautiful appearance.

[0006] 2. Different types and sizes of nuts vary greatly in appearance and dimensions, making it difficult for one machine to handle all kinds of nuts.

[0007] 3. The original nut cutting process has low production efficiency and is difficult to meet different cutting requirements, such as double-sided single-cut or double-sided double-cut. Summary of the Invention

[0008] To address the problem that existing cutting machines are difficult to be compatible with various nuts, this invention provides a highly compatible nut double-sided continuous cutting machine.

[0009] The technical solution adopted by this invention to solve its technical problem is:

[0010] A highly compatible nut double-sided continuous slicing machine, comprising:

[0011] The frame is equipped with an annular guide rail.

[0012] A feeding mechanism, which is installed above the frame;

[0013] A cutting mechanism, the cutting mechanism comprising a blade for cutting a nut at least one side;

[0014] The clamping mechanism moves along a circular guide rail. It includes a fixed clamp and a movable clamp. During movement, the distance between the movable and fixed clamps changes. The nuts fall from the feeding mechanism onto a bearing plane between the fixed and movable clamps. Before cutting, the nuts are gradually clamped by the fixed and movable clamps, and after cutting, they are gradually released. The clamping mechanism also includes a spring, positioned on the side of the fixed clamp away from the movable clamp. The spring ensures that nuts of different sizes receive similar clamping force while preventing them from breaking due to excessive clamping force.

[0015] A drive mechanism is provided to drive the clamping mechanism to move along the annular guide rail.

[0016] Furthermore, the movable clamp is slidably connected to the fixed clamp, the movable clamp is provided with rollers, the frame is provided with a guide ring rail, the guide ring rail is provided with a guide groove, the rollers move along the guide groove, the guide groove includes a variable pitch guide groove, the variable pitch guide groove is curved, thereby causing the rollers to drive the movable clamps closer to or away from the fixed clamp.

[0017] Furthermore, the variable pitch guide groove is a cam-shaped guide groove.

[0018] Furthermore, the fixed clamp includes a fixed end connecting frame and a clamp fixed end, and the movable clamp includes a movable end connecting member and a clamp movable end. Both the fixed end connecting frame and the movable end connecting member are connected to the drive mechanism. The fixed end connecting frame and the movable end connecting member are fixedly connected by a guide rod. The clamp fixed end and the clamp movable end are slidably disposed on the guide rod. The spring is provided between the clamp fixed end and the fixed end connecting frame. The clamp movable end is connected to the roller through a connecting rod.

[0019] Furthermore, the fixed end connecting frame is fixed with a fixed plate. One end of the spring abuts against the fixed plate, and the other end abuts against the fixed end of the clamp. An adjusting bolt connects the fixed plate and the fixed end of the clamp. The head of the adjusting bolt abuts against the fixed end of the clamp, and the tail of the adjusting bolt protrudes from the fixed plate and is fitted with an adjusting nut. The spring constant of the buffer spring is adjusted by the adjusting bolt at the fixed end to match the processing requirements of nuts of different sizes and shapes, ensuring that the clamp is adaptable to different types of nuts.

[0020] Furthermore, the movable end connector is fixed with a first clamping plate, and the first clamping plate is fixed with a second clamping plate via a support column. A linear bearing is installed between the first and second clamping plates, and the connecting rod is slidably connected to the linear bearing. Constrained by the guide rod and the linear bearing, the movable end reciprocates in the clamping direction under the drive of the cam roller, completing clamping and releasing.

[0021] Furthermore, the fixed end of the clamp is provided with a first clamping groove, and the movable end of the clamp is provided with a second clamping groove. The edges of the first clamping groove and the second clamping groove are provided with guide slopes to guide the nuts to the bottom of the groove.

[0022] Furthermore, the guide ring rail is movably mounted on the frame, and the frame is equipped with a positioning mechanism for positioning the guide ring rail.

[0023] Furthermore, the feeding mechanism includes a feeding tray fixedly connected to the frame, a turntable rotatably mounted in the feeding tray, a plurality of temporary storage holes in the turntable, and a feeding port at the bottom of the feeding tray. When the turntable rotates to the point where the temporary storage holes are aligned with the feeding port, the nuts contained in the temporary storage holes fall into the feeding port. The feeding tray is also fixed with a baffle, which covers both sides of the feeding port and is located above the turntable.

[0024] Furthermore, the cutting mechanism includes an upper cutting mechanism and a lower cutting mechanism. The upper cutting mechanism is provided with a feed inlet, which is connected to the feed port through a feeding channel. The upper surface of the lower cutting mechanism is the bearing surface, and the lower cutting mechanism is provided with a discharge port. A feeding mechanism is also fixed on the frame, and the discharge port is connected to the feeding mechanism through a feeding channel.

Before cutting, the nuts are gradually clamped by the fixed clamp 41 and the movable clamp 42, and after cutting, they are gradually released by the fixed clamp 41 and the movable clamp 42. The clamping mechanism 4 also includes a spring 43, which is positioned on the side of the fixed clamp 41 away from the movable clamp 42. The drive mechanism 6 drives the clamping mechanism 4 to move along the annular guide rail 5. In this invention, the driving mechanism includes a chain driving device. The clamping mechanism 4 is connected to the chain of the chain driving device and moves back and forth along the annular guide rail 5. In this way, the clamping mechanism 4 shuttles between the various cutting mechanisms 3, and works with the feeding mechanism 2 and the cutting mechanism 3 to clamp and release the nuts.

[0052] like Figures 9-12 The movable clamp 42 is slidably connected to the fixed clamp 41. The movable clamp 42 is equipped with a roller 423, and the frame 1 is equipped with a guide ring rail 7. The guide ring rail has a guide groove 71. The roller 423 moves along the guide groove 71, which includes a variable-pitch guide groove 711. The variable-pitch guide groove 711 is curved, thereby causing the roller 423 to move the movable clamp 42 closer to or away from the fixed clamp 41. Preferably, the variable-pitch guide groove 711 is a cam-shaped guide groove.

[0053] The fixed clamp 41 includes a fixed end connecting frame 411 and a clamp fixed end 412. The movable clamp 42 includes a movable end connecting frame 421 and a clamp movable end 422. Both the fixed end connecting frame 411 and the movable end connecting frame 421 are connected to the drive mechanism 6. The fixed end connecting frame 411 and the movable end connecting frame 421 are fixedly connected by a guide rod 44. The clamp fixed end 412 and the clamp movable end 422 are slidably disposed on the guide rod 44. A spring 43 is provided between the clamp fixed end 412 and the fixed end connecting frame 411. The clamp movable end 422 is connected to a connecting rod 4232. A connecting shaft 4231 is connected to the connecting rod 4232. A roller 423 is installed on the connecting shaft.

[0054] The fixed end connecting bracket 411 is fixed with a fixed plate 413. One end of the spring 43 abuts against the fixed plate 413 and the other end abuts against the clamp fixed end 412. An adjusting bolt 414 is connected between the fixed plate 413 and the clamp fixed end 412. The head of the adjusting bolt 414 abuts against the clamp fixed end 412, and the tail of the adjusting bolt 414 passes through the fixed plate 413 and is fitted with an adjusting nut 415.

A linear bearing 427 is installed between the first clamping plate 424 and the second clamping plate 426, and the connecting rod 4232 is slidably connected to the linear bearing 427.

[0056] The clamp fixed end 412 is provided with a first clamping groove 4121, and the clamp movable end 422 is provided with a second clamping groove 4221. The edges of the first clamping groove 4121 and the second clamping groove 4221 are provided with guide slopes to guide the nuts to the bottom of the groove.

[0057] The guide ring rail 7 is movably mounted on the frame 1, and the frame 1 is equipped with a positioning mechanism for positioning the guide ring rail 7. Specifically, the variable pitch rail 7 is connected to a linear motor, a slide rail 11 is fixed on the frame 1, a slider 12 is slidably mounted on the slide rail 11, the guide ring rail 7 is fixedly connected to the slider 12, and a locking seat 13 is also fixed on the frame 1.

[0058] like Figures 3-5 The feeding mechanism 2 includes a feeding tray 21 fixedly connected to the frame 1. A turntable 22 is rotatably provided in the feeding tray 21. The turntable 22 is provided with a plurality of temporary storage holes 221. The bottom of the feeding tray 21 is provided with a feeding port 211. When the turntable 22 rotates to the point where the temporary storage holes 221 are aligned with the feeding port 211, the nuts contained in the temporary storage holes 221 fall into the feeding port 211. The feeding tray 21 is also fixed with a baffle 212, which covers both sides of the feeding port 211 and is located above the turntable 22.

[0059] like Figures 6-8 The cutting mechanism 3 includes an upper cutting mechanism 31 and a lower cutting mechanism 32. The clamping mechanism 4 shuttles between the upper cutting mechanism 31 and the lower cutting mechanism 32. The upper cutting mechanism 31 is provided with a feeding port 311, which is connected to the feeding port 211 through the feeding channel 8. The upper surface of the lower cutting mechanism 32 is a bearing surface for bearing the falling nuts. The lower cutting mechanism 32 is provided with a discharging port 321. A discharging mechanism 9 is also fixed on the frame 1. The discharging port 321 is connected to the discharging mechanism 9 through the discharging channel 10.

[0060] The upper cutting mechanism 31 includes an upper cutting seat and an upper cutting tool 312. The upper cutting tool 312 is connected to an upper cutting drive shaft 313. The upper main shaft of the upper cutting tool 312 is connected to a small pulley and drives the upper cutting drive shaft 313 through a large pulley. The upper main shaft can be adjusted in position on the upper cutting seat by adjusting screws, etc. The upper cutting drive shaft 313 is connected to an upper drive synchronous pulley. The upper drive synchronous pulleys between adjacent cutting mechanisms are connected by an upper synchronous belt. The lower cutting mechanism 32 includes a lower cutting seat and a lower cutting tool 322. The lower cutting tool 322 is connected to a lower cutting drive shaft 323. The lower main shaft of the lower cutting tool 322 is also connected to a small pulley and drives the lower cutting drive shaft 323 through a large pulley. The lower cutting drive shaft 323 is connected to a lower drive synchronous pulley. The lower drive synchronous pulleys between adjacent cutting mechanisms are connected by a lower synchronous belt.

[0061] In this invention, the feeding mechanism 2, the cutting mechanism 3 and the clamping mechanism 4 are arranged in a one-to-one correspondence and are arranged side by side on the frame. Of course, according to actual needs, an integrated feeding mechanism 2 can be used, and the nuts are fed to each cutting mechanism 3 through the feeding channel respectively. The unloading can be done by an integrated unloading container to collect the nuts falling from each unloading channel.

[0062] Working principle:

[0063] 1. Feeding: The feeding tray 21 is a mechanism for sorting a large number of unprocessed nuts. It needs to separate and sort the large number of nuts that enter to avoid a large number of nuts entering the cutting system at the same time, which would lead to cutting failure. In order to improve the sorting and conveying efficiency of the feeding tray 21, the turntable 22 is driven by a motor to rotate at an appropriate speed to bring the pile of nuts into the inlet in an orderly manner and queue them into the clamp 41. Considering the processing efficiency, three feeding trays are set up.

[0064] 2. Clamping: The clamping mechanism 4 moves along the annular guide rail 5 under the drive of the drive mechanism 6, continuously circulating through the working space between the upper cutting mechanism 31 and the lower cutting mechanism 32. Simultaneously, the variable-pitch guide groove 711 of the guide rail 7 limits the clamping of the nuts during feeding and releasing them during discharge. One side of the clamping mechanism 4 is a movable clamping end 422 restricted by the variable-pitch guide groove 711, and the other side is a fixed clamping end 412 connected to the spring 43. The fixed clamping end 412 can achieve different clamping effects with varying stiffness by adjusting the adjusting bolt 414. The movable clamping end 422, driven by the variable-pitch guide groove 711, clamps the nuts at the feeding port 311 and releases them when they are transported to the discharge port 321 after cutting. The guide ring rail 7 is mounted on four sets of linear slide rails 11. The roller 423 is connected to the movable end 422 of the clamp. The clamping range of the clamp can be adjusted by adjusting the position of the guide ring rail 7. After adjustment, it is locked and fixed by bolts to ensure the stability of the guide ring rail 7.

[0065] 3. Cutting: The lower cutting mechanism 32 has a top surface, and the upper cutting mechanism 31 has a bottom surface. The bottom surface assists in the clamping and limiting of the nuts, and can also adjust the cutting depth and width of the blade as needed, working with the clamp to cut the upper and lower surfaces of the walnut at the set cutting depth and width. The top and bottom surfaces can, to some extent, offset the influence of the cutting force, avoiding excessive longitudinal sliding during cutting and affecting the cutting quality. To match the feeding tray device, three upper and lower cutting mechanisms are also provided.

[0066] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
